' Application filed June 9,1908. Serial No. 437,485.

1'0 all whom it may concern:

Be it known that I, GEORGE E. HULSE, a

citizen of the United States, residing at Newark, in the county of Essexand State of New Jersey, have invented certain new and usefulImprovements in Mantle Protectors and Holders, of which the following isa full, clear, and exact description, such as will enable others skilledinthe art to which it appertains to make and use the same.

This invention relates broadly to mantle fixtures, but inasmuch ascertain advantages characteristic thereof prominently appear in 11s moreintense aspect as a unitary mantle container and appher, it will beconducive to a more complete disclosure to detail such embodimentthereof.

This invention has in view, among other objects, the provision of aunitary fixture in which the mantle, as well as the means instrumentalin attaching it to a depending are removably contained within cialshipments' and handlings of the device.

Another object falling within the contemplation of this invention is toprovide a mantle and its supporting means with a protector of suchperforate or open work structure that substantially the full andcomplete light emitting qualities of the mantle will beusefully'realized, while at the same time the mantle will be wellprotected against accidental abrasions or contacts.

In general, this invention seeks to provide a unitary device of thenature mentioned, which will be eflicient in operation, capable of beinghandled with facility, and which will be of a simple constructionsuitable for being manufactured at a reasonable a one of the manyavailable expedients which may be employed for securing the protector tothe mantle support. Fig. 3 is a vertical section of a box or receptaclewhich may be employed for containing the unitary device shown by Fig. 1,and which serves on the one hand to attach such device to the burnertube, and on the other hand as a convenient shipment casing. Fig. 4 is avertical section showing the device applied to a depending burner tubepreparatory to removing the receptacle or box. Fig. 5 is a verticalelevation showing the gers and the receptacle in the act of removmg thelatter from the mantle and the protector.

Continuing now by way of a more detailed description, making occasionalreference' to the drawings as indicated by the reference characters, 1denotes a spool or mantle sup ort which carries a mantle 2 depending romthe lower end thereof and preferably permanently secured to such end.This mantle spool may, of course, assume divers shapes and may becomposed of various materials, but I prefer to construct the same ofcompact asbestos and give the same an annular or cylindrical shape, suchas that indicated by the drawings. This mantle support ma be providedwith interior threads 3 a apted to be screwed on an exteriorly threadedcounterpart 4, which may be the lowermost extremity of a dependingburner tube. A suitable abutment such as that indicated by 5 willsuflice for limiting the extent of movement onto the burner tube of themantle supporting spool.

As a means instrumental in transmitting the rotation of the receptacleto the mantle support, when the latter is being secured to the burnertube, I have employed an intervenin member which also serves, in thisembodiment of my invention, as a cage for guarding the mantle againstinjury. This member, designated generally by A, comprises a plurality ofoutwardly and downmaking this attachment will be apparent,

and as exemplifying the same, I have here shown one method in which theupper ends of the legs 6 are provided with flattened segmental ends 8having prongs 9 which are embedded in the material of the spool 1. Awire 10 may encircle such ends to prevent a withdrawal of the prongs. Ofcourse, while I have shown the protector A in attached relation tO tlIGmantle sup ort, it will'be evident that the same may e integraltherewith, if desired, and the whole ma be stamped of one piece.

ooperating with the aforesaid parts, and

' more directly with the protector A, is a suitable receptacle 11, whichmay be cylindrical or poly onalin form, and which may be provide with acap 12 and a bottom 13. The protector and the parts attached theretoWlll. be inserted as a unit in this rece tacle until the perforatebottom plate, w ich rests upon the bottom 13 of the receptacle, and thedownwardly and outwardly'flaring legs 6 frictionally engage against thesides of the receptacle, as-is shown more clearly in Fig. 4 with the capin place, this selfcontained device may be shipped and handled withgreat facility.

, The operation of replacin a mantle upon a burner tube by means 0' thehereindisclosed'invention is most sim le. The cap 12 will be removed andthe on of the burner tubes screwed into the mantle spool 1 until asufficiently tight relation between the two has been brought about.Owing to the fact that the legs 6 bear against the annular wall of thereceptacle there will be sufiicient friction to prevent a relativedepending movement between the protector A and the receptacle. I Withthe parts properly positioned the receptacle or casing may be instantlyremoved by simply pulling the same downwardly which leaves the mantleand protector on the burner tube in condition for immediate use.

As many changes could be made in the above construction and manyapparently widely different embodiments of this invention could be madewithout departin from the scope thereof, it is intended that a l mat tercontained in the above description or shown in the accom anying drawingsshall be interpreted as il ustrative and not in a limiting sense. 1

Having described my inventio what I claim as new and desire to securbyLetters Patent is:

1. A device of the nature disclosed comprising in combination, a mantlesupport adapted to be detachably secured to a burner tube, a mantlepermanently secured to said support 1n vpendent relation therewith, a

" protector secured to said mantle support encaging said mantle, and areceptacle resistingly containing said protector adapted to be Withdrawntherefrom.

2. A device of the nature disclosed comprising in combination, aninteriorly threaded mantle support adapted to be detachably threaded onan exteriorly threaded burner tube, a mantle permanently secured inpendent relation to said support, a protector secured to said supportand encaging said mantle, and a receptacle resistingly containing saidprotector and adapted to be withdrawn therefrom.

p 3. A device of the nature disclosed, comprising in combination, amantle support adapted to be detachably secured to a burner tube, amantle permanently depending from said support, a protector secured tosaid support and roviding a plurality of outwardly 'exten ing armsencaging said mantle, and a receptacle frictionally engaging said armsand adapted to be withdrawn therefrom.

4. A device of the nature disclosed comprising in combination, a mantlesupport adapted to be detachably secured to a burner tube, a mantlepermanently depending from said support, a protector secured to saidsupport having a plurality of arms spreading downwardly and outwardly toencage said mantle, and a cylindrical receptacle frictionally engagingthe outermost portions of said protector and adapted to be manuallywithdrawn therefrom.
